Hi MatijaSo no matter how spamassassin is called, in both cases IMHO it should get the full text/rfc822 email with header any body and get the same results.Agreed. if your mail is indeed in correct format, there are few things that I'd check: - has the MIMEdefang been instructed to reload to pick up new rules?Absolutely.- has the reload succeeded, specifically: - e.g. file permission problem might have "spamassassin -t" running as root succeed, while MIMEdefang running as unprivileged user might fail)Well, in my understanding, spamassassin only nees read access to rules, and as 'rules' are applied, this is not a generic issue. TO_IN_SUBJ rules exist in 72_active.cf and active.list, both are world readable, so unless I overlooked something weird, I can exclude this.
could it be this SA bug (fixed in trunk) ? https://bz.apache.org/SpamAssassin/show_bug.cgi?id=8388 Giovanni
But I will add a shell to my 'defang' user under which the milter is running and run spamassassin as this user, just to make sure.- syntax error might case MIMEdefang to abort reloading and use old configuratinfilter:~# spamassassin --lint May 12 16:11:45.572 [7633] warn: Found From: [email protected] filter:~# mimedefang.pl -f /etc/mimedefang-filter -test Prototype mismatch: sub main::message_contains_virus: none vs () at /etc/mimedefang-filter line 142. Prototype mismatch: sub main::entity_contains_virus: none vs ($) at /etc/mimedefang-filter line 163. Found From: [email protected] Filter /etc/mimedefang-filter seems syntactically correct. Does not look like severe errors- you can check by e.g. adding some other always-hitting rule in same config file and see if that one matches in both cases or also only in cmdline "spamassassin -t" - also, check the logs that MIMEdefang might produceMIMEDefang just runs fine and logs what is reported by SpamAssassin.
